SPECIFICATION forming part of Letters Patent No. 359,731, dated March 22, 1887.

Application filed October 12, 1886. Serial No. 215,907. (No model.)

To all whom it may concern:

Be it known that I, EDMUND LUNKENI-IEI- BEER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to those lubricators having an ascending sight-feed 5 and the first feature of my improvements comprises a novel combination of reservoir, oil-discharge tube, steam-pipe, external detachable head, condenser, and sight-chamber, which devices are arranged as follows: The reservoir has at bot tom a hollow screw-threaded shank or other attachment wherewith the lubricator is socured in place, and the channel of this shank communicates with the oil-discharge tube, being, in fact, a continuation of the latter, the upper end of said tube being screw-threaded to engage with the neck of the external and detachable head, which neck is fitted within a nozzle ofthe reservoir. This nozzle projects from the upper end of the reservoir, and the external head applied to said nozzle has a lateral exposed duct leading into the top of a sight-feed chamber, whose lower end is provided with a customary nipple and a pipe leading up within said reservoir. This exter nal lateral duct connects with the oil-discharge tube that clamps the outer head to the reservoir, but has no communication whatever with the pipe that admits steam to the condenser, it being desirable in this class of lubricators to have one channel for the ascending steam and another separate and distinct channel for the descending oil, in order that there may be no interference between these opposing currents. Furthermore, it is desired to arrange the stcam-pipe in such a manner as not to heat the oil in the reservoir to a higher degree than can possibly be avoided. I accordingly locate said pipe within the oil-discharge tube so as not to come in contact with the oil, and carry the upper end of the aforesaid steampipe up within the condenser, which latter is mounted upon the detachablehead, previously alluded to. The condensed water from this elevated vessel escapes through a valveguarded port in said head, and then runs down within a pipe to the bottom of the reservoir, for the purpose of gradually displacing the oil con tained therein, and thereby insuring the desired feed, as hereinafter more fully described.

The annexed dra-wing is an axial section of my improved lubricator, the sight-chamber and its connections being shown in elevation.

The oil fount or reservoir A, which is usually cylindrical, may have at bottom a hollow screw-threaded shank, B, wherewith the lubricator is secured in place. Occupying an axial position within the reservoir is the oildischarge tube 0, the channel of which is a continuation of the bore of the aforesaid hollow shank or equivalent connection. This tube has no lateral branches or bends of any kind, but is carried vertically up through the reservoir, being screw-threaded at D to engage with the neck E of the external and detachable head, F, a packing-ring, G, being interposed between said head and the upper end of nozzle E. This nozzle is integral with the upper end of the reservoir, and its bore receives the aforesaid cylindrical neck E. The external head, I has an outer lateral duct, 1, the inner end of which communicates with the oil-discharge tube 0, while the opposite end of said duct leads into the top of the sight chamber J, having a customary nipple, K. Extending from the bottom of this sightchaniher is a pipe, L, that is carried up within the reservoir and almost to the top of the same. Furthermore, the external head, F, has a channel or port, M, controlled by a condenservalve, N, the outlet of said port beingin communication with a pendent pipe, 0, reaching almost to the bottom of the reservoir.

Coupled to the upper end of the detachable head F is a condenser, P, surmounted by a removable plug, It, the slackening of which latter allows an escape of air when steam is first admitted into the lubricator. Located within this condenser is a steam-pipe, S, threaded at s, to be screwed into the head F, that portion S of the pipe below said thread being somewhat reduced. in diameter, for a purpose that will presently appear. The extreme upper end of this steam-pipe S S s is nicked or slotted at T, to receive a screwdriver or other similar turning-implemcnt.

U is a customary filling-plug, and V a draincock for the reservoir. \V is a valve at the bottom of the sight-chamber J, and, if desired, another valve may be applied to the top of said chamber, as suggested by the dotted lines X.

In fitting together the various parts of this lubricator, the screw-threaded oil-discharge tube 0 serves as a tie or hinder that securely clamps the external detachable head, F, to the reservoir A, and thus centralizes the neck E of said head within the nozzle H of said reservoir, the steam-pipe S S being screwed into said head as far as the thread 8 will permit. Consequently said pipe occupies an axial. position both within the condenser I? and oildischarge tube 0, and the lower end of said pipe preferably projects a slight distance below the hollow shank B. The fount is filled through plug U, and the other plug, 1%, is unscrewed sufficiently to allow a proper ventage of air when steam is admitted into the lubricator, which then operates as follows: Steam enters through the pipe S S and fills the chamber P, the condensed water formed in said chamber being permitted to escape down the port M and pipe 0, thusgradually displacing and elevating the oil contained insaid fount. The floating oil then escapes fromsaid fount through the pipe L, nipple K, sight: chamber J,and external duct, 1, into the internaltube, 0. After entering the tube 0 the oil flows directly down into the steam pipe or chest, or other part to be lubricated. It will thus be seen that two separate and distinct channels are provided at the base of the lubricator, one channel being adapted to permit the ascent of steam into the condenser and the other channel to allow a descent of oil from the fount. Therefore, these separate channels prevent any interference between the ascending and descending currents, and cause the feed to be perfectly regular and uninterrupted, the rate of discharge being regulated by the condenser-valve N. should get choked up with scales or other sediment, the plug It can be detached, the point of a turning-tool bcinsertcd in the nick T, and said pipe can then be unscrewed from the head F and drawn out at the top of the condenser. The pipe can then be clcanedand reinserted, or a new one applied in its place. This withdrawal of the steam-pipe also enables a wire to be passed down through the center of the lubrieator for the purpose of cleaning out the tube 0. It will thus be seen that the plug R and bodily-detachable steam-pipe S S permit the ready cleaning of those passages which are the most liable to become choked up, and without removing the lubricator from.

If the pipe S S" of my invention thesectious S S may be of the same cliameter,but separate,aud be screwed into the head, so as to communicate wlth each other; but as this construction would prevent the bodily withdrawal of the lower section through the condenser for the purpose of cleaning the tube 0, it is not recommended for all kinds of lubrieators. W'hichever of these constructions may be adopted, it is evident thesteam-pipe S S will be a separate and distinct conductor passing up within the oil-discharge tube 0 and having no contact withthe oil in the reservoir. Therefore there will, be no danger of the oil being boiled by the heat radiated from the steam-pipe, which serious difficulty frequently happens with those lubricators in which the ascending current of steam and descending current of oil traverse the same channel. It will also be noticed that the lateral branch I of theioiltube is wholly external with referenceitothe reservoir A, which externallocation not only prevents radiation of heat into said reservoir,

but it also facilitates the manufacture of thelubricator and renders it more easy to clean, inspect, and repair the same.
